α decay of high-spin isomers in N = 84 isotones
Research output: Contribution to journal › Article
Abstract
The superfluid tunneling model is applied to the calculation of half-lives of the observed α decays in N=84 isotones. Results of our calculations are compared to experimental data on the ground-state α decays along the isotonic chain from 144Nd to 159Re. Good agreement is found. The α decays of the known high-spin isomers in 155Lu, 156Hf, 157Ta, and 158W are also well reproduced, once a reduction in the pairing strength is taken into account. This includes reproduction of the main features of the recently observed fine structure from 155Lu (25/2-) and 156Hf (8+). Predictions for the α-decay fine structure of 157Ta (25/2-) and 158W (8+) high-spin isomers are presented.
